    Performance idea

    Laurent Etiemble Expert

      Hi,

      I have made some experiment with JBoss AOP. I have quickly implemented a pool/factory for Invocation and InvocationResponse.

      Advantages :
      - reduce the number of object creation drastically
      - almost 10% faster on dummy test (1000000 invocations)

      Drawbacks :
      - each Invocation creation must be done through the pool/factory
      - when the final target is invoked the Invocation must be released
      - each InvocationResponse creation must be done through the pool/factory
      - when the caller grab the InvocationResponse, he must release it

      Most of the creation/release code is in the aop core classes. So it is fairly transparent to most of the already defined aspects.
      But it defines a contract for Interceptor writers if they have to break the interception chain (either invocation or response). Leaks can occurs it the contract is broken

      Any thoughts ?

      Laurent.
